What is return in stored procedure?

The RETURN statement is used to unconditionally and immediately terminate an SQL procedure by returning the flow of control to the caller of the stored procedure. To return multiple output values, parameters can be used instead. Parameter values must be set prior to the RETURN statement being executed.

What are in and out parameters in stored procedure?

An input/output parameter is a parameter that functions as an IN or an OUT parameter or both. The value of the IN/OUT parameter is passed into the stored procedure/function and a new value can be assigned to the parameter and passed out of the module. An IN/OUT parameter must be a variable, not a constant.

Can a stored procedure return multiple values?

Multiple values will be returned from Stored Procedure by returning comma separated (delimited) values using Output Parameter. Output Parameter is supported in Stored Procedures of all SQL Server versions i.e. 2000, 2005, 2008, 2008R2, 2012 and 2014.

What is SQL store procedure?

(Back to Top) A stored procedure is a set of SQL statements that can be executed on the database. It is stored as a object in the database.
